COMBINED HARROW, ROLLER, AND SEEDER.

I I Application filed February 10, 1883. (No model.)

'lowing' description, and more particularly pointed out in the claims.

The object of my invention is to provide an effect1ve and easy-workin gagricultural implement of this class.

In the accompanying drawings, Figure 1, Sheet 1, is a perspective viewof mydevice. Fig. 2, Sheet 2, is a plan of the divided roller B. Fig. 3is a detail showing tooth E and the means for connecting it. Fig. 4.shows tooth F entire. Fig. 5 shows the parts of said tooth. Fig. 6 isavertical section of lubricator-box. Fig. 7 is a plan view of same. Fig.8, Sheet 3, is a section showing seeder and apron Z.

Let A represent the main frame of the device, across the rear portion ofwhich is mounted, upon independent shafts, the twopart roller B. This isto allow the frame to turn, as is well known.

In the front portion of the frame is the harrow 0. This consists ofatransversely-mounted shaft, a, carrying disks D, across which aresecured in a spiral course a number of parallel strips, d, upon whichthe teeth E are secured. These teeth are shown in Fig. 3, and consist ofatriangular piece, the hypotenuse of which is preferably curved. Theyhave a notch, e, to fit them onto the edge of the strip (1, and they aresecured thereon by a setscrew, f, passing up from beneath through thestrip and entering the rear of the tooth. The tooth shown in this figureI find advantageous-for use in soft or loose ground; but where the earthis hard and stiff I find a tooth, F, (shown in Figs. 4, 5,) tobe better.This consists of a shank, 9, having the same kind of a notch, e, to fitit on the strip (2, and being adapted to be secured thereonin the samemanner. The outer end of the shank is split, and to one inner edge issecured a square piece or lug, 71.

A square plate, 1', having beveled edges and a central square hole orsocket, fits between the split ends of the shank, the square piece hentering its central socket, and is there secured by a screw, j. Thiscutting-plate 2' may be easily removed, and when dull may have anotheredge presented; and instead of being fitted in to cut square, it may beso fitted as to present its corner to cut the ground. This tooth actsmore like a plow in cutting rather than in scratching the ground.

In placing the teeth upon the spiral strips I do not make them followone another, but place each row a little to one side, so that in cuttingor harrowing they shall operate over the entire surface of the ground.

Hinged to the rear of the frame A is the tongue G, from the rear crossend of which are supported standards H. In the tops of these is mounteda shaft, I, carrying a pulley, J, on one end, and a-pulley, K, on theother.

A belt, is, extends from a pulley, 1), upon the end of the roller-shaftto the pulley K, and abelt, Z, extends from the pulley J.to a pulley, m,upon the end of the shaftc of the harrow 0. Thus multiplied revolutionis imparted from the traction-roller B to the harrow. This revolution ofthe harrow is not impeded by its teeth striking the ground, for but asingle tooth of a strip strikes at atime. This is on account of theposition of the strips (1; and it has the further advantage of producingbut a slight shock or jar, and enabling me for that reason to use alight frame for the harrow. Again, the harrow, in rapidly revolvingforward, has a tendency to assist the progress of the machine.

L represents the lever by which the harrow is raised and lowered. It isfulcrumed on the rear of the frame A by a standard, M, and .'is joinedto the center of the frame by a standard, as shown.

O11 account of the standards H being on the tongue G, when the harrow israised by the lever L, the driving-belts 7c and Zare slackened and nopower is wasted. When the harrow is lowered, the belts tighten up again.position of these standards and their height requires some kind ofbrace, and for this purpose I have the centrally-hinged brace-rods 0'attached to the tops of the standards and to The the sides of the frame.These are so. hinged as to bend upward, but not downward below astraight line; The reason for the bracing is to prevent the belts, whenthe harrow is at work, from straining the standards, and thus looseningthe belts. when they should be tight.

These braces, by being hinged, allow the movement of the frame A. andstill stiffen the standards I-I.

In order to accomplish the movement of the hinged braces to allow theframe to move, I have the bent lever P, the ends of which are journaledon the driving-shaft I. The sides of this lever have projecting arms 1),with bifurcated ends fitting over and under the upper half of the hingedbraces. These serve to hold down or liftup the braces, as will be seen.center of the lever and passes back over a pulley in the top of therudder-post R and down to the lever L, to the end of which it issecured. Now, when the end of the lever is depressed, the cord Q pullsup the bent lever I, and raises it a distance equal to the length of thearc inscribed by the handle end of lever L. This lever 1?, through itsbifurcated arms thus ben ds upward the hinged braces O faster than theworking end of the main lever rises, so that the eifect of the movementof the main lever upon the frame A may take place without thetoggle-braces O interfering by reason of their being elevated tooslowly. The arms p, supporting the hinged braces, render them as muchbraces when bent as when straightened out.

The rudder-post R is journaled in the rear end of the tongue, and isconnected firmly with the rudder-wheel r. This wheel is construeted witha fiat center and two flanges on its edges for entering and taking holdof the ground. The fiat center of the wheel is designed to roll downthat portion of the ground missed by the center of the main roller B,

which is constructed in two parts, the inner' edges of which areseparated to allow the center brace to enter, Fig. 2.

The operator stands on the projecting end of the tongue and turns therudder-post by means of a handle, 0*. In order to set it in any desiredposition there is a plate or disk, S, secured upon it just above thetongue. Inthe rim or edge of the plate are holes 8, with which the pointof a spring, T, is adapted to engage to hold the plate. A small lug, t,upon the spring is for the driver to put his foot upon to depress thespring and throw its point out of engagement with the plate whendesired. The plate S, being fitted close to the tongue, prevents therudder-post or rudderwheel from leaning, but keeps both erect.

In order to set the main lever L when adjusted, the rudder-post R isprovided with a number of peripheral grooves, u.

Upon the sides of the lever are pivoted pawllevers U, the ends of whichare made concave, as shown, and are held in engagement with A cord, Q,is attached to the the grooves u by means of springs w. By pressing inon the levers U their concave ends are thrown out of engagement with thegrooves u, and the lever L may be adjusted.

It is of prime necessity that the harrow 0 shall turn in the bearin gswith the least friction. In order to accomplish this I have a means forlubricating its bearings, which are particularly shown in Figs. 6, 7.

V represents the box or bearing of the shaft 0, and 'v is the oil-holein its top. The bearing V has a small chamber, a, alongside of it, inwhich is journaled ashort rubber roller, W, lying parallel with shaft 0.The surface of this roller has made in it a spiral groove, 00. The oilis poured into the box and collects in its bottom. The shaft and rollerimpinge, and by the revolution of the former the latter is revolved andconstantly supplies the oil to the shaft, thus rendering the deviceself-lubrieating.

In the center of the frame A is the seeder X. This consists of a trough.having a longitudinal slot, y, in its bottom.

In the trough is a shaft, y, having a spiral flange, y The shaftprojects through the trough, and carries a pulley, z. A belt, z, fromthis pulley to a pulley, 2', upon the end of the main harrow-shaft,furnishes revolution to the flanged shaft whereby the seed is agitatedin the trough and caused to fall down through the slot .3 and, further,when the revolution of the harrowrylinder ceases, that of theseedrfeeding device ceases also.

Connected with the bottom of the seedtrough is a curved directing-apron,Z, the edge of which extends down nearly to the ground, and as close aspossible to the harrow, so as to deposit the seed directly in the cutsmade by the barrow-teeth.

From the construction and position of my rudder and post the driver mayadd a comfortable seat without interference.
